Definitions

  • the invention relates to a snow brush roller for interchangeable attachment to a road service vehicle, as a bristled brush roller which is rotatably suspended on the vehicle about its horizontal longitudinal axis, which can be adjusted obliquely to the vehicle longitudinal direction, opposite to the wheels of the forward-moving vehicle.
  • Snow brushes of this type are known per se, see for example DE-B-1 117, and they are used for the so-called black clearing of snow-covered roads. Tests have shown that their combined use with a snow plow and / or a salt spreading device is particularly advantageous. In particular, they make it possible to significantly reduce the amount of salt spread.
  • the use of a snow brush roller is advisable only up to snow depths of a few centimeters, e.g. B. in the wake of another snow removal device.
  • the snow sweeping roller produces a lateral snow ejection according to its inclination, provided that the roller rotates at a certain minimum speed.
  • Such a snow roller can either be attached to the front, rear or between the wheel axles on the road service vehicle.
  • the invention is based on providing a snow brush roller of the type mentioned at the outset with a control device which enables low-wear operation of the snow brush roller with low energy consumption and which is particularly suitable for use in combination with a moving snow removing device.
  • Feature a means that the roller speed increases or decreases with the speed of the road service vehicle.
  • This rule takes into account the amount of snow depending on the vehicle speed.
  • a certain minimum throw distance regardless of the respective vehicle speed, e.g.
  • the setting of a minimum amount is defined in feature c) the roll peripheral speed (w-min) is essential; this minimum speed should be set at around 5 km / h.
  • the sweeping task can still be fulfilled by each snow element being caught several times by the roller until it is ejected from the vehicle area.
  • the control device is individually programmable, the essential input data being listed in claim 4.
  • the ratio of the circumferential roller speed to the vehicle speed is essentially to be selected as a function of the snow depth; the minimum roller circumferential speed (w-min) is generally a fixed value that is independent of the sweeping operation; if necessary, it also depends on the roll length.
  • the roller diameter should be entered as precisely as possible, taking bristle wear into account. While the input data mentioned can be entered by manual setting, the respective vehicle speed must be continuously converted into a corresponding input signal, which is done, for example, via a tachometer generator.
  • the control device In order to warn the driver of the road service vehicle before this situation is reached, it is proposed according to the invention that the control device generates a warning signal when the maximum roller circumferential speed (w-max) has been reached after an upper vehicle speed (f-max) has been exceeded.
  • a value for the maximum roller circumferential speed obtained from practical driving operation can be assumed to be around 30 km / h. Of course, this value depends on the maximum possible output of the roller drive, in the case of a hydraulic drive thus on the maximum possible delivery rate of the hydraulic system. If the driver hears the warning signal, he will react by reducing the vehicle speed. This not only ensures that the roller circumferential speed is always greater than the vehicle speed, but also that the ratio of the two speeds is maintained in the sense of the set proportion.
  • control device comprises control electronics, the output signal of which is a proportional flow control valve in the pressure line of a vehicle side driven hydraulic pump for regulating the oil flow for a hydraulic roller drive.
  • control electronics the output signal of which is a proportional flow control valve in the pressure line of a vehicle side driven hydraulic pump for regulating the oil flow for a hydraulic roller drive.
  • a version with a controllable hydraulic pump or constant pump is possible. While in the controllable hydraulic pump the oil flow is regulated in such a way that a constant pressure difference is always maintained between the pressure side of the hydraulic pump and the consumer pressure, in the constant pump the oil flow remains unchanged in the event of fluctuations in consumer pressure; Here, the partial flow not consumed by the consumer is directed to the tank against the consumer pressure.
  • the hydraulic pump is either powered by a power take-off or by a power take-off.
  • the diagram shows the speed control characteristic of a snow roller according to the invention, different speed ratios w / f between values 1 and 2 being given.
  • the proportions can be overlaid by a selectable minimum roller circumferential speed (w-min), so that the proportionality curve only begins at a driving speed f1 in order to end when the maximum roller circumferential speed w-max is reached at the driving speed f2.
  • the values entered in the diagram refer to a speed ratio w / f - 1.3. According to this example, the minimum roller circumferential speed w-min from driving speed f0 to f1 is retained. When the driving speed f1 to f2 increases, the proportion w.1.3 x f applies.
  • the performance limit of the hydraulic system is reached with w-max.
  • the control device generates a warning signal so that the driver of the road service vehicle can reduce its speed.
  • the roller circumferential speed remains constant at w-max.
  • the diameter ratio of the worn roll (diameter d) to the new roll (diameter D) is taken into account as a correction factor, e.g. B. according to the formula
  • FIG. 1 shows a road service vehicle with a road salt container 2 on the loading platform 3.
  • the front axle of the vehicle 1 is not shown.
  • a snow plow is attached to the front of vehicle 1.
  • the snow residue not removed from the snow plow is ejected to the side from the vehicle area by a snow roller 4, which is attached to the underside of the vehicle from the wheel axles.
  • a salt spreader 5 connected to the rear of the vehicle 1 ensures an ice-free, non-slip road surface.
  • the snow roller 4 rotates clockwise according to the drawn view.
  • Arrow P1 i.e. opposite to the rotation acc.
  • the snow-sweeping roller is driven hydraulically by means of a hydraulic pump 6, which is flange-mounted on the rear of a gear 7, which is connected on the drive side to a motor PTO 8.
  • the hydraulic lines or other elements of the hydraulic circuit are not shown in the drawing, with the exception of the hydraulic motor 9 (FIG. 2) for driving the snow roller 4 and the hydraulic tank 10 attached to the underside of the vehicle, which as a unit with an associated flow control valve 11 and control electronics 12 is shown.
  • the snow roller 4 is rotatably mounted in a frame made of lateral frame parts 13 and a cross member 14 connecting them.
  • a U-bracket 15 made of box sections is welded to the cross member 14 and is pivotably suspended about a horizontal axis 16 for raising or lowering the sweeping roller 4.
  • the brush roller 4 is shown in the raised position, which corresponds to the dash-dotted line 17 in Fig. 1.
  • a hydraulic cylinder 18 is used to raise or lower the sweeping roller, which is articulated on the one hand on the cross member 14 and on the other hand on a support arm 19 of a vehicle-side suspension device.
  • This suspension device comprises vehicle-mounted brackets 20 which are flanged to the opposite longitudinal frame supports 21 of the vehicle 1.
  • a lifting cylinder 18 is articulated on a support arm 19 which is fixedly connected to the upper end of the bearing part 24 and which, on the other hand, is articulated to the cross member 14.
  • a pivot pin 25 is formed with a vertical axis of rotation.
  • a holding part 26 is pivotally attached, on which in turn the U-bracket 15 is suspended pivotably about the horizontal axis 16.
  • a pair of cylinders can also be provided.
  • Fig. 3 the street sweeper roller 4 including suspension is shown mounted on a height-adjustable chassis 27, with only one axis 28 of the chassis 27 with the wheels 29 being drawn according to the sectional view of the suspension.
  • FIG. 2 shows the snow sweeping roller 4 in a top view of the vehicle 1, showing the essential vehicle outline in the right swivel position, with a swivel cylinder 30 being extended.
  • the swivel cylinder 30 is articulated on the one hand on the right holding strut 23 and on the other hand on a bolt 31 which is firmly connected to the holding part 26 (cf. FIG. 3).
  • FIG. 4 shows a hydraulic diagram with an adjustable hydraulic pump 6 for driving the hydraulic motor 9 of the snow roller 4.
  • the respective driving speed (f) is determined via a tachometer generator 32.
  • Whose signal is amplified in the control electronics 12; the desired ratio of the circumferential roller speed to the vehicle speed and the minimum circumferential roller speed are entered manually into the control electronics.
  • Their output signal actuates a proportionally controllable flow control valve 33, which controls the oil flow on the pressure side of the hydraulic pump 6 in the manner of an orifice, in such a way that there is always a constant pressure difference between the pressure side (at a) of the hydraulic pump 6 and the consumer pressure (at b) is maintained.
  • the two pressure values (at a, b) form input signals for pump control.
  • the flow control valve 33 is integrated in the control system of the hydraulic pump.
  • the hydraulic pump 6 is driven via a PTO shaft 8 and a clutch 34 to the vehicle engine 35.
  • a warning signal (at 37) is triggered via a pressure switch 36. It means that the maximum delivery rate of the hydraulic system and thus also the maximum roller peripheral speed have been reached. If the vehicle speed increased further, the proportion between the circumferential roller speed and the vehicle speed entered into the control electronics could no longer be maintained.
  • a switch-on valve 38 is shown in the “off” position, the hydraulic pump 6 conveying into the reservoir 40 via a short-circuit line 39.
  • FIG. 5 shows a hydraulic diagram for regulating the contact pressure of the sweeping roller 4.
  • this contact pressure adjustable. This ensures that the snow roller either lies on the ground with its own weight or, depending on the setting, with a lower weight.
  • This relief is expediently carried out hydraulically via the existing lifting cylinder or cylinders.
  • Fig. 5 z. B. done by hydraulic biasing the return line 41 from the lifting cylinder 18 to the tank 40, wherein a pressure relief valve 42 is turned on in the return line 41.
